As well as yes/no questions, you can also form tag questions with 吗 (ma). Tag questions are quick questions that are tagged on the end of a sentence to ask for confirmation. In English, this is often done with "right?" or negatively with "isn't it?"
The easiest way to do this in Chinese is to add some kind of confirmation word and 吗 (ma) on the end of the sentence.
As you can see below, the pattern typically involves words like 好 (hǎo), 对 (duì), 是 (shì), or 可以 (kěyǐ), followed by 吗 (ma).
……， 好 / 对 / 是 / 可以 + 吗？
By placing these on the end of a sentence, you can soften a suggestion or request confirmation.

Nǐmen jiàn guo, duì ma?
